How to Estimate Pavement Roughness: Beyond International Roughness Index [PDF]

, 2019
The standard way to describing the road\u27s roughness it to use a single numerical characteristics called International Roughness Index (IRI). This characteristic describes the effect of the road roughness on a vehicle of standard size. To estimate IRI,

Predicting Pavement Condition Index for Cold‐Region Highways Using an ENET‐XGBoost Coupled Model

Applied Research, Volume 5, Issue 5, October 2026.
An ENET–XGBoost framework combines regularized feature selection and nonlinear residual correction for cold‐region pavement prediction. Traffic loading dominates deterioration; the model achieved R2 = 0.969 in back‐calculation, while Markov and scenario analyses indicate a 25% risk of Fair‐or‐below condition in 2026 and PCI of 74.2–77.5 by 2028 ...

RIPC Protects Against Renal Ischaemia–Reperfusion Injury by Activating SIRT3/Parkin‐Mediated Mitophagy

Journal of Cellular and Molecular Medicine, Volume 30, Issue 19, October 2026.
ABSTRACT Remote ischaemic preconditioning (RIPC) protects against renal ischaemia–reperfusion injury (IRI), yet its precise mechanism remains incompletely understood, particularly regarding the role of mitochondrial quality control. This study investigated whether SIRT3‐dependent mitophagy mediates the protective effects of RIPC against acute kidney ...

Evaluation of the methodologies used to generate random pavement profiles based on the power spectral density: An approach based on the International Roughness Index

Ingeniería e Investigación, 2017
The pavement roughness is the main variable that produces the vertical excitation in vehicles. Pavement profiles are the main determinant of (i) discomfort perception on users and (ii) dynamic loads generated at the tire-pavement interface, hence its ...

A Study on the Road Conditions Assessment Obtained from International Roughness Index (IRI): Roughometer Vs Hawkeye

Simetrikal: Journal of Engineering and Technology, 2019
Study is aimed to find out what is the representation of IRI (International Roughness Index) from the Roughometer results if it was used as substitute of IRI from the Hawkeye results on the road conditions assessment, which is the hawkeye device is included in the Class I category of roughness measurement devices, while the Roughometer is in the Class ...

Life cycle costs and mid-term performance of a geogrid-stabilized pavement section, an economical and sustainable approach, case study, RN-39 Honduras [PDF]

E3S Web of Conferences
When we talk about mechanical stabilization of granular layers with geogrids in roadway applications, we often mention that these pavements have a better performance along the time and a reduced cost along the whole life cycle.

A Comprehensive Review of Tire Abrasion: Mechanisms, Parameters, and Wear Rates in the Era of Vehicle Electrification

Applied Research, Volume 5, Issue 4, August 2026.
The type of vehicle (internal combustion, hybrid, electric) has a direct effect on its tire wear particle emission. As expected, electric vehicles generate higher amounts due to their higher weight and torque, but regenerative breaking must also be accounted for.
